Regression Analysis > Linear Relationship. What is a Linear Relationship? A linear relationship means that you can represent the relationship between two sets of variables with a line (the word “linear” literally means “a line”). In other words, a linear line on a graph is where you can see a straight line with no curves.
Linear relationships such as y = 2 and y = x all graph out as straight lines. When graphing y = 2, you get a line going horizontally at the 2 mark on the y-axis. When graphing y = x , you get a ...
Linear relationship is a statistical term used to describe the relationship between a variable and a constant. Linear relationships can be expressed either in a graphical format where the variable ...
The graph clearly shows that the slope is continually changing; it isn’t a constant. With a linear relationship, the slope never changes. In this example, one of the fundamental assumptions of simple regression analysis is violated, and you need another approach to estimate the relationship between X and Y.
linear relationship: A relationship of direct proportionality that, when plotted on a graph, traces a straight line. In linear relationships, any given change in an independent variable will always produce a corresponding change in the dependent variable. For example, a linear relationship between production hours and output in a factory means ...
Another special type of linear function is the Constant Function ... it is a horizontal line: f(x) = C. No matter what value of "x", f(x) is always equal to some constant value. Using Linear Equations. You may like to read some of the things you can do with lines:
Linear equations like y = 2x + 7 are called "linear" because they make a straight line when we graph them. These tutorials introduce you to linear relationships, their graphs, and functions.

A linear relationship exists when two quantities are proportional to each other. If you increase one of the quantities, the other quantity either increases or decreases at a constant rate. For example, if you get paid $10 an hour, there is a linear relationship between your hours worked and your pay.
Modeling with tables, equations, and graphs See how relationships between two variables like number of toppings and cost of pizza can be represented using a table, equation, or a graph. Linear models
The follow up covered a study that rejected a linear model, and instead grouped respondents in to “traditional”, “egalitarian” and “counter-cultural” couples. Despite the claims of the original study, they found that the relationships were only really linear within the groups, but that it was 3 different linear relationships.
